Asta Series R123 Regulating Valve - Single Seat Two-Way for Flow Control

"Purpose: cutting off or regulation of the working medium flow in the pipeline, full or partial closing of the seat channel by the plunger with the help of electric or pneumatic actuator, which is in conjunction through the valve stem. Design features:
- hermetically sealed construction;
- seat diameter without narrowing - does not obstruct the flow inside the pipeline at full opening of the valve;
- possibility to adjust the flow capacity according to linear or equal per cent dependence;
- different types of plug seals (EPDM, PTFE or metal-to-metal);
- self-sealing spring-loaded chevron gland assembly;
- two stem guides to increase plunger positioning accuracy and reduce the effects of high pressure during plunger movement;
- a repairable design that allows the valve capacity to be changed during maintenance."
